Viair 45012 Dual Silver 450C Compressor Pack
The Viair 45012 Dual Silver Pack supplies two 12V 450C compressors and control components for a tank-based air installation. The included 110/145 PSI pressure switch defines switching points, while continuous-duty operation is stated at 100 PSI rather than the 150 PSI pressure maximum.
Specifications and included details
- Two 12V silver 450C compressors with thermal overload protection.
- 100% duty cycle at 100 PSI; maximum working pressure 150 PSI.

Before ordering
Plan tank, plumbing, wiring and circuit protection around the installation instructions. A ten-gallon maximum does not establish an included tank. Two compressors and a pressure switch do not guarantee adequate continuous airflow for every pneumatic tool.
Product questions and answers
Is 150 PSI the pressure-switch shutoff point?
No. The included switch is listed to turn off at 145 PSI and on at 110 PSI. The 150 PSI maximum compressor pressure is a separate specification.
Does 44 A apply to each compressor?
The listing identifies 44 A as the combined maximum draw of the pack, not a per-unit value.
Does 100% duty cycle apply at 150 PSI?
The stated continuous-duty rating applies at 100 PSI. Do not transfer it to the separate 150 PSI maximum without manufacturer confirmation.
